8-Channel Differential DAS with 18-Bit, Bipolar, Simultaneous Sampling ADC
The AD7609 operates from a single 5 V supply and can accommodate ±10 V and ±5 V true bipolar differential input signals while sampling at throughput rates up to 200 kSPS for all channels. The input clamp protection circuitry can tolerate voltages up to ±16.5 V. The AD7609 has 1 MΩ analog input impedance regardless of sampling frequency. The single supply operation, on-chip filtering, and high input impedance elimi-nate the need for driver op amps and external bipolar supplies. The AD7609 antialiasing filter has a −3 dB cutoff frequency of 32 kHz and provides 40 dB antialias rejection when sampling at 200 kSPS. The flexible digital filter is pin driven, yields improvements in SNR, and reduces the −3 dB bandwidth.
